N/F/SMA Connector Multitool
Description
This is an update to my previous design which can be found here: https://www.thingiverse.com/thing:6163080 I've added a third spanner size to this lightweight field tool. It is good for types N, F and now SMA connectors. It looks like a Keith Haring sculpture of a jumping dog! The tool is handy for my portable QO-100 antenna which has a Messi and Paoloni N-connector on the Tx helix and two generic F-connectors on the LNB (Rx and Freq Ref). The added SMA connector spanner comes as a convenient bonus. Since high torques are not required and indeed best avoided, the tool can be printed in plastic. I used PETG for its heat and weather resistance properties as well as its ease of use. ABS filament would provide better strength but is more challenging to print. Tweaking the size printed by a few percent may be necessary to accommodate your particular printer tolerances. I now often use fluorescent paracord on my gear. It helps my old eyes find stuff in the dark recesses of my roving rucksack or in generally low light conditions. 73 Paul, F5VMJ https://twitter.com/F5VMJ
